Example of [Ants3D](https://skfb.ly/FFAu) reversible cellular automaton (RCA) evolution using [stop motion](https://blog.sketchfab.com/animating-voxels-sketchfab-stop-motion/). The same configuration was shown earlier in a [post](https://ayvlasov.wordpress.com/2013/07/31/flying-bricks-ca/) using gif animation. The stability of the RCA is rather illusion - even collision of two ants with slightly different distance than here would produce [Big Bang](https://skfb.ly/FDxp).
